Abstract :
A synthetic test bench with two different voltage sources is described to investigate bearing currents, based on a lumped element model of an electrical motor. The aim of this synthetic test bench is to reproduce the voltage and current wave form at the bearing, which actually happen in bearings of inverter-fed motors, to investigate the influence of these electric quantities on bearing failures.
